Materials Data on Sr2TmRuO6 by Materials Project

Abstract

Sr2TmRuO6 is Orthorhombic Perovskite-derived structured and crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Sr2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Sr–O bond distances ranging from 2.56–2.91 Å. Tm3+ is bonded to six O2- atoms to form TmO6 octahedra that share corners with six equivalent RuO6 octahedra. The corner-sharing octahedra tilt angles range from 22–23°. All Tm–O bond lengths are 2.20 Å. Ru5+ is bonded to six O2- atoms to form RuO6 octahedra that share corners with six equivalent TmO6 octahedra. The corner-sharing octahedra tilt angles range from 22–23°. There is four shorter (1.98 Å) and two longer (1.99 Å) Ru–O bond length. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 5-coordinate geometry to three equivalent Sr2+, one Tm3+, and one Ru5+ atom. In the second O2- site, O2- is bonded in a 5-coordinate geometry to three equivalent Sr2+, one Tm3+, and one Ru5+ atom. In the third O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Sr2+, one Tm3+, and one Ru5+ atom.
